This article struck some chords with me as I grew up strict Scottish Presbyterian and then had some experience of evangelical churches. I couldn’t accept all the rules of my childhood and never felt at home in other churches. They could be quite cliquey and I felt that it was difficult to express doubt. I also had a very difficult experience when a lay church member ‘prophesied’ for a sick relative with the result that they became very distressed and much sicker.
I like your last quote. I was agnostic for many years. I tried to live life to the full, in the moment. I practised yoga and tai chi and eventually this brought me to an awareness of the presence and love of God. This (plus a period of suffering) brought me full circle back to the church, although this time I became Catholic. If you’re interested, I have blogged about this here https://scotinprogress.com/2017/06/01/reconciliation/
By the way, I am not an expert, but I think that any Catholic can perform the Sacrament of Baptism. However, usually only in extreme cases when someone’s life is in danger and there is no priest available.
